Congratulations on learning the proper spelling instead of the incorrect Argyle you were using.
Here's the cut and paste, with a little more information, from my previous response to your inquiry.
The mascot and symbolism came from a Gent named J. Scott Campbell, a proud Scotsman who resided near the Madison County village of Leisure. (Lay-zure not Lee-zure)
Based on the history of the Scottish county of Argyll and surrounding area.
